Blast Furnace Tap Hole / Mudgun Mass

VVEL offers a complete range of Tap Hole products to meet the widely varying demands of Indian Blast Furnaces & COREX plant. The intrinsic properties of VVEL Tap Hole mixes are:

  1. Good workability to facilitate extrusion.

  2. Consistency of Structure to Prevent oozing out of nose of the gun.

  3. Controlled coking-out time to ensure adequate strength of extruded material. 

  4. Lower volatile to minimise fumes and gas evaluation.

  5. Good resistance to oxidation and slag attack.

  6. Ease of drilling at the time of Tap Hole opening.

  7. Good Shelf life.

We have also developed and established our Tap Hole mass in COREX unit.

BLAST FURNACE TROUGH / RUNNER MASS

VVEL offers improved range of carbon bonded Trough / Runner services products to meet the demanding service requirements of today's Indian Blast Furnaces. The properties of these products are:

1. Erosion resistance from iron.
2. Corrosion resistance from slag.
3. Non Wettability to iron and slag.
4. Low porosity to resist metal penetration.
5. Thermal stability and shock resistance.
6. Structural integrity.

Note : The properties of Tap Hole Mass & Runner Mass are Tailor made to suit the requirement of Blast Furnaces of various capacities. (From Mini Blast Furnace of 175 M3 capacity to Blast Furnace of 4000 M3 capacity).
